'determined' is the definition.
The answer and definition can be both to do with communicating as well as being past participle verbs.
Perhaps you can see an association between them that I don't see?

'umpire in total' is the wordplay.
'umpire' becomes 'judge' (I can't justify this - if you can you should give a lot more credence to this answer).
'in' is an insertion indicator.
'total' becomes 'add' (synonyms).
'judge' put inside 'add' is 'ADJUDGED'.
